The reaction of Et₃GeCH:CH₂ + Et₃SiOH → Et₃SiO-Ge-Et₃ + CH₂:CH₂ has been studied using quantum chem. methods. Geometries of reactants, transition states, and products have been optimized resp. at the B3LYP/6-311+g(2d,2p) level. The rate constants were evaluated using canonical variational transition state theory (CVT) and canonical variational transition state theory with small-curvature tunneling contributions (CVT/SCT) over the temperature range of 200-3500K. The CVT/SCT rate constants exhibit typical non-Arrhenius behavior, and a three-parameter rate-temperature formula has been fitted as follows: k(T)=1.43 × 10^-38T^5.41exp(-13200/T) (in units of cm³ mol.^-1s^-1).

Li, Xiuru published the artcileMultifunctional Surface Modification of Gold-Stabilized Nanoparticles by Bioorthogonal Reactions, Recommanded Product: (2R,3S,4S,5S,6R)-2-(Hydroxymethyl)-6-(4-isothiocyanatophenoxy)tetrahydro-2H-pyran-3,4,5-triol, the publication is Journal of the American Chemical Society (2011), 133(29), 11147-11153, database is CAplus and MEDLINE.

Nanocarriers that combine multiple properties in an all-in-one system hold great promise for drug delivery. The absence of technol. to assemble highly functionalized devices has, however, hindered progress in nanomedicine. To address this deficiency, the authors have chem. synthesized poly(ethylene oxide)-β-poly(ε-caprolactone) (PEO-b-PCL) block polymers modified at the apolar PCL terminus with thioctic acid and at the polar PEO terminus with an acyl hydrazide, amine, or azide moiety. The resulting block polymers were employed to prepare nanoparticles that have a gold core, an apolar polyester layer for drug loading, a polar PEO corona to provide biocompatibility, and three different types of surface reactive groups for surface functionalization. The acyl hydrazide, amine, or azide moieties of the resulting nanoparticles could be reacted with high efficiencies with modules having a ketone, isocyanate, or active ester and alkyne function, resp. To demonstrate proof of principle of the potential of multisurface functionalization, nanoparticles that have various combinations of an oligo-arginine peptide were prepared to facilitate cellular uptake, a histidine-rich peptide to escape from lysosomes, and an Alexa Fluor 488 tag for imaging purposes. It has been shown that uptake and subcellular localization of the nanoparticles can be controlled by multisurface modification. It is to be expected that the modular synthetic methodol. provides unique opportunities to establish optimal configurations of nanocarriers for disease-specific drug delivery.

Gomola, Kinga published the artcileAn optically uniaxial antiferroelectric smectic phase in asymmetrical bent-core compounds containing a 3-aminophenol central unit, Formula: C7H9NO, the publication is Journal of Materials Chemistry (2010), 20(37), 7944-7952, database is CAplus.

Two series of asym. bent-core compounds possessing 3-aminophenol and its N-Me derivative have been synthesized. The asymmetry arose from the different linkages between the central unit and the chem. chains of the substituents, and in two cases also from different lateral substituents. The mesomorphic properties were investigated by differential scanning calorimetry, polarizing optical microscopy, switching current and electro-optical measurements, X-ray anal., and second-harmonic generation. All materials possessing 3-aminophenol as a central unit showed liquid crystalline properties, and two of them exhibited the orthogonal smectic phase (SmA family phase) and very stable columnar phases, while the N-Me analogs exhibited no mesophase. Because of the optically uniaxial nature, double switching current peaks, and SHG activity associated with a distinct threshold elec. field, this orthogonal smectic phase was assigned to a novel type, which has a short-range antiferroelec. order with a long-range randomized polar plane (SmAP_AR).

Wang, Haolan published the artcileTargeting MCL-1 in cancer: current status and perspectives, Recommanded Product: 2-((4-(4-Bromophenylsulfonamido)-1-hydroxynaphthalen-2-yl)thio)acetic acid, the publication is Journal of Hematology & Oncology (2021), 14(1), 67, database is CAplus and MEDLINE.

A review. Myeloid leukemia 1 (MCL-1) is an antiapoptotic protein of the BCL-2 family that prevents apoptosis by binding to the pro-apoptotic BCL-2 proteins. Overexpression of MCL-1 is frequently observed in many tumor types and is closely associated with tumorigenesis, poor prognosis and drug resistance. The central role of MCL-1 in regulating the mitochondrial apoptotic pathway makes it an attractive target for cancer therapy. Significant progress has been made with regard to MCL-1 inhibitors, some of which have entered clin. trials. Here, we discuss the mechanism by which MCL-1 regulates cancer cell apoptosis and review the progress related to MCL-1 small mol. inhibitors and their role in cancer therapy.

Huang, Pingsheng published the artcileFluorine Meets Amine: Reducing Microenvironment-Induced Amino-Activatable Nanoprobes for ¹⁹F-Magnetic Resonance Imaging of Biothiols, SDS of cas: 2240-88-2, the publication is ACS Applied Materials & Interfaces (2018), 10(22), 18532-18542, database is CAplus and MEDLINE.

¹⁹F-magnetic resonance imaging (MRI) is of great significance for noninvasive imaging and detection of various diseases. However, the main obstacle in the application of ¹⁹F-MRI agents stems from the unmet signal sensitivity due to the poor water solubility and restricted mobility of segments with high number of fluorine atoms. Herein, the authors report a kind of intracellular reducing microenvironment-induced amino-activatable ¹⁹F-MRI nanoprobe, which can be used for specific imaging of biothiols. In principle, the nanoprobe has an initial architecture of hydrophobic core, where the trifluoromethyl-containing segments are compactly packed and ¹⁹F NMR/MRI signals are quenched (“OFF” state). Upon encountering sulfydryl, the strong electron-withdrawing 2,4-dinitrobenzenesulfonyl groups are excised to recover secondary amino groups, whose pK_a is 7.21. As a consequence, the mol. weight loss of the hydrophobic segment and the protonation of amino groups induce significant disturbance of hydrophilic/hydrophobic balance, leading to the disassembly of the nanoprobes and regain of spin-spin relaxation and ¹⁹F NMR/MRI signals (“ON” state, T₂ up to 296 ± 5.3 ms). This nanoprobe shows high sensitivity and selectivity to biothiols, enabling intracellular and intratumoral imaging of glutathione. The authors’ study not only provides a new nanoprobe candidate for biothiols imaging in vivo but also a promising strategy for the mol. design of real water-soluble and highly sensitive ¹⁹F-MRI nanoprobes.

Lu, Jiaxin published the artcileFood Waste Management Employing UV-Induced Black Soldier Flies: Metabolomic Analysis of Bioactive Components, Antioxidant Properties, and Antibacterial Potential, Synthetic Route of 90-64-2, the publication is International Journal of Environmental Research and Public Health (2022), 19(11), 6614, database is CAplus and MEDLINE.

Food waste, as a major part of municipal solid waste, has been increasingly generated worldwide. Efficient and feasible utilization of this waste material for biomanufg. is crucial to improving economic and environmental sustainability. In the present study, black soldier flies (BSF) larvae were used as carriers to treat and upcycle food waste. Larvae of the BSF were incubated with UV light for 10, 20, and 30 min at a wavelength of 257.3 nm and an intensity of 8 W. The food waste utilization efficiency, antioxidant assays, antibacterial activity, and bioactive metabolites without and with UV treatment were determined and compared. This showed that the BSF larvae feed utilization rate was around 75.6%, 77.7%, and 71.2% after UV treatment for 10, 20, and 30 min resp., contrasting with the non-UV induced group (73.7%). In addition, it was perceived that the UV exposure enhanced antioxidant and antimicrobial properties of BSF extracts, and the maximum values were observed after 20 min UV induction time. Moreover, UV-induced BSF extracts showed an improved metabolic profile than the control group, with a change in the amino acids, peptides, organic acids, lipids, organic oxides, and other derivatives This change in metabolomics profile boosted environmental signaling, degradation of starch, amino acids, sugars, and peptide metabolism It was concluded that the bioconversion of food wastes using UV-induced BSF larvae can enhance the generation of a variety of functional proteins and bioactive compounds with potent antioxidant and antimicrobial activity. However, more studies are required to exploit the efficiency of UV treatment in improving BSF′s potential for upcycling of food wastes.

Lyu, Shuxia published the artcileEffect of rare earth elements on vitamin C fermentation by mixed cultures, Formula: C6H10O7, the publication is International Journal of Agriculture and Biology (2014), 16(6), 1135-1140, database is CAplus.

In recent years, the research on rare earth metals has expanded to the field of microbiol. In China, the production of Vitamin C is through mixed culture fermentation, which transforms L-sorbose to 2-keto-L-gulonic acid (2-KGA), the precursor of Vitamin C. In this study we compared the yields of 2-KGA by an acid-producing strain of Ketogulonigenium vulgare that was co-cultured with different companion bacterial strains in the presence of four light rare earth elements, lanthanum, cerium, neodymium, and samarium at selected concentrations We found that all of the tested rare earth elements had a promoting effect on 2-KGA production at concentration up to 5 mM. At or above 10 mM, the yield of 2-KGA was reduced. When cultured sep. with 5 mM of given rare earth elements, the growth of two companion bacterial strains (Bacillus megaterium 25-B and B. subtilis A9) were both significantly reduced, while that of the K. vulgare strain was enhanced.

Gong, Xiao-li published the artcileEffects of Bacillus megaterium 2980’s spore formation on 2 KGA production of Gluconobacter oxydans, Safety of (3S,4R,5S)-3,4,5,6-Tetrahydroxy-2-oxohexanoic acid, the publication is Gongye Weishengwu (2013), 43(6), 49-53, database is CAplus.

In order to determine the relationship between the spore formation of Bacillus megaterium 2980 (B, m 2980, called companion bacterium) and Gluconobacter oxydans (G. o, called acid-producing strain) in vitamin C two-step fermentation, the effects of the culture supernatant, the cytosol and the mixed component solution of companion bacterium which cultured for 12 h (not forming spores) and 36 h (forming spores) on the growth of G. o and its synthesizing ability of 2-keto-L-gulonic acid (2-KGA) were studied through the anal. of B. m 2980 growth characteristics. The results showed that when the B. m 2980 spores did not form, the culture supernatant, the cytosol and mixed component solution had low effects on the growth of acid-producing strain and its 2-KGA production The cytosol of B. m 2980 promoted the growth and 2 KGA production of G. o greater than that of the culture supernatant. After the spore formation of B. m 2980, the culture supernatant and mixed component solution of B. m 2980 affected growth and 2-KGA production of G. o significantly.
